Three-dimensional interactions of a half-plane crack with point forces, dipoles and moments

Closed form solutions in terms of elementary functions are derived for stress intensity factors along the edge of a half-plane crack induced by point forces, dipoles, centers of expansion and moments. Locations and orientations of these "stress sources" are arbitrary. The solid is assumed to be either transversely isotropic (with the crack parallel to the plane of isotropy) or isotropic. © 1997 Published by Elsevier Science Ltd
